Greta Gerwig’s much-anticipated “Little Women” just screened in L.A. and NYC. A social media embargo has lifted on Gerwig’s adaptation of Louisa May Alcott’s famous novel and it appears that there are fans, but also many people with reservations, which is quite odd as many film critics tend to not want to express too many negative things in their Twitter reactions so as to appease the studio bigwigs that watch their every move. Suffice to say, this doesn’t look like it’s going to be a “Lady Bird” triumph for Gerwig.
